the process is governed by the upliftment of the rocks from beneath the surface due to tectonic movements like folding, faulting, collision, these rocks are now subjected to different types of denudational agents like wind, water, glacier , they get eroded and transported , hence deposited in a basin to form a sedimentary rock.

Three major groups of rocks are defined: igneous , sedimentary , and metamorphic . The scientific study of rocks is called petrology , which is an essential component of geology.

Igneous rock is one of the three main rock types. Igneous rock is formed through the cooling and solidification of magma or lava. Igneous rock may form with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.
